Patent number: 11190890Abstract: An acoustic testing apparatus may include connections for multiple devices under test (DUTs) to support simultaneous testing of two or more miniature electroacoustic devices. The acoustic testing apparatus may allow the testing of multiple DUTs with a ratio of less than one reference microphone per DUT. Thus, the speed of testing DUTs may be increased without adding significant cost through additional reference microphones. For example, a single reference microphone may be used to test two or four DUTs coupled together through an acoustic test cavity.Type: GrantFiled: April 12, 2017Date of Patent: November 30, 2021Assignee: Cirrus Logic, Inc.Inventors: Aleksey Khenkin, Kevin Stoddart, Gordon Cowan, Keith Getz

Patent number: 9681242Abstract: A MEMS microphone system suited for harsh environments. The system uses an integrated circuit package. A first, solid metal lid covers one face of a ceramic package base that includes a cavity, forming an acoustic chamber. The base includes an aperture through the opposing face of the base for receiving audio signals into the chamber. A MEMS microphone is attached within the chamber about the aperture. A filter covers the aperture opening in the opposing face of the base to prevent contaminants from entering the acoustic chamber. A second metal lid encloses the opposing face of the base and may attach the filter to this face of the base. The lids are electrically connected with vias forming a radio frequency interference shield. The ceramic base material is thermally matched to the silicon microphone material to allow operation over an extended temperature range.Type: GrantFiled: August 21, 2014Date of Patent: June 13, 2017Assignee: INVENSENSE, INC.Inventors: Kieran P. Harney, Jia Gao, Aleksey Khenkin
